Hm... I don't know if an editor can help you with your syntax errors. Even once the syntax errors are out of the way, there are still a ton more errors to disconver that you have to track down in other ways.

Now that this is out of the way, you might want to give ActiveState Komodo a try. It is putting red scribbles under syntax errors during you type and works pretty well in this regard. Once you got all the syntax errors out of the way, it might even help you with it's built-in visual debugger and reg-ex doctor.

One more time: You should try to learn the syntax of perl, instead of letting an editor guess the syntax for you. In some cases you might not have access to YOUR editor when you most need it.
